Achilles vs Eli vs Kiddo

Achilles gets his sword. Eli gets his machete. Beatrix is wielding the Green Destiny from Crouching Tiger Hidden Dragon. Eli is still under biblical protection and Achilles' heel has been made as invincible as the rest of him. Beatrix is fully under the protection of the Green Destiny.

3-way swordfight to the death in Central Park, Manhattan
Bloodlusted; no PIS/CIS; who takes this?

Achilles was invincible in the film?

No he was not........

He will be given an adamantium blade. Best of luck to him.

If you look up the definition of invulnerable

1. Impossible to harm, damage, or defeat: incapable of being wounded, injured, or harmed

The definition of Invincible is different

Invincible
1. incapable of being conquered, overcome, or subdued

So I would call him both until he was hit in the heel because he was incapable of being conquered or overcome, and incapable of being wounded until he took damage to his heel.
